Not a carb expert. Have both butterflies with only .020" showing. The passenger side exhaust is noticeable richer than driver. All 4 idle mixture screws adjusted the same. Other symptom is car idles at 1050 and over 3 minutes pulls back to 800 rpm. Other than that it runs like a champ. any suggestions appreciated.

i think its a mighty demon, it has the idle eaze on the air cleaner hold down but it doesn't appear to do much when i adjust. air bleeds have been blown through with gum out.
